My check engine light went on today, if I accelerate fast my engine goes weak, and starts shutting cylinders down and I have to shut engine off to reset computer and it will run normal again, with engine light still on, till I get on it again. The harder I push it the more cylinders that shut down. Engine code p0300 p0301 p0302 p0303 and p0304.

Those codes are misfire code and are hard to diagnose even for a pro. Have a pro look at it or wherever you get your car serviced. This could be anything wrong with the motor/sensors/injectors or fuel pump.

Misfires are extremely hard to findif it's not a plug wire, coil or a compression problem. Unfortunately it is hard for even tech s to find it. I'll submit for a refund.
